Red Sea ReefGate Valve upgrade kit for Reefers with 32mm / 1" pipingMeet ReefGate Red Seas new high precision gate valve, designed specifically for reef aquariums. ReefGate uses all plastic reef safe components. It maintains a consistent water level in the downflow box and eliminates trickling noise, as each rotation of its handwheel opens closes the valve by only 1mm, allowing users to finely balance the water flowing down with the water that is being pumped up. ReefGate is integrated into all REEFER G3 systems and
